This is a tattoo of the prairie grass Andropogon gerardii, or big blue stem. My masters research involved land disturbance, mycorrhizae and soil properties associated with this & two other common prairie plants.
Also notice that this tattoo is over a wicked scar from a car accident where I shattered my calcaneus. More than half of a prairie plant is below ground, keeping the plant alive during regular disturbances (such as fire or grazing). The extensive root system over my repaired heal symbolizes stability, strength and recovery. I had the obscure idea, but the artist (Kit) made my botanical mumblings a reality.
